Description

GAS BAG MODULE COVERED WITH A PROTECTIVE COVERING
Description
The invention relates to a gas bag module with a case-like housing having an open side, with a folded inflatable gas bag and with a gas generator connected to the gas bag, wherein the gas bag is folded in the housing and the open side of the housing is overlapped and covered by a protective covering.
A gas bag module with the above-mentioned features is described in DE 41 12 939 Al. In the known gas bag module, the protective covering is formed as a shrink film shrunk onto the housing, spanning over at least the open side of the housing. In the edge region of the housing opening, a sharp-edged strip, having saw teeth, is fastened on the outer side of the housing. When, after triggering of the gas generator, the gas pressure increases in the interior of the gas bag, a corresponding pressure is exerted onto the protective covering by the gas bag which is pushing outwards through the opening of the housing, allowing the protective covering to tear open along the saw tooth strip, so that the housing opening is exposed for the emergence of the gas bag.
The known gas bag module entails the disadvantage that the application of the shrink film is complex in the process step which is to be instituted separately.
The invention is therefore based on the problem of constructing a gas bag module with the features named in the introduction, so that the mounting of the gas bag module with application of the protective covering is simplif ied . The solution to this problem, including advantageous embodiments and further developments of the invention can be seen from the content of the claims which follow this description .
In its fundamental idea, the invention makes provision that the protective covering, provided with a pre-set tear line, is fastened at its one end inside the housing and with its other free end, overlapping the open side of the housing, is secured on a flange, protruding outwardly from the housing wall, mounted on the housing, wherein the flange has at least one opening, directly adjoining the transition between housing wall and flange, for the guiding through of at least one tongue formed on the free end of the protective covering, and a holding nose is provided, projecting from the housing wall into the interior of the opening and to be brought into engagement into a holding recess formed in the insεrtable tongue of the protective covering .
The invention firstly departs from the concept of the shrinking on of the protective covering onto the housing, entailing a particular effort, and provides a separate protective covering consisting of any suitable material, which is fastened by its one end in a suitable manner in the interior of the housing, is guided out of the housing and is then covered over the open side of the housing. In this region, overlapping the open side of the housing, the protective covering is provided with a pre-set tear line so that the protective covering, with a corresponding exertion of pressure by the inflating gas bag, tears open along the pre-set tear line. To fasten the free end of the protective covering on the housing, a particular design of mounting- and holding openings on the housing is provided in cooperation with holding tongues formed on the protective covering. It is important here that the free end of the protective covering is wrapped around the upper edge of the housing and is secured in a path along the associated housing wall, without gores being produced between the protective covering and the housing edge or the flange, into which the gas bag could reach when being folded into the housing or into which the gas bag could move on being unfolded, so that the gas bag could thereby be damaged.
According to an example embodiment of the invention, provision is made that over the extent of flange and housing wall on the one hand and of the associated end of the covering on the other hand, a plurality of openings and tongues of the protective covering, to be secured therein, are arranged.
According to an example embodiment of the invention, provision is made that the holding nose, projecting into the opening, is arranged so as to be sunken with respect to the surface of the flange facing away from the gas generator. Hereby, a jamming of the protective covering between the flange and, for example, an instrument panel or a steering wheel cover, is prevented, which in a manner known per se with a corresponding mounting of the gas bag module in the vehicle in an arrangement overlapping the open side of the housing are connected with the housing.
Provision may be made that the transition between housing wall and the flange protruding therefrom in the region of the opening immediately adjoining the housing wall is constructed with a rounding. Hereby, damage to the tongue of the protective covering by a rim, constructed with a sharp edge, between housing wall and flange or by a vehicle part resting on the gas bag module or its flange, is avoided .
In alternative embodiments of the invention, provision may be made that the protective covering is secured by its one end in the interior of the housing on the gas bag, which is folded in the housing, or by means of the gas generator projecting into the housing.
In the drawings, an example embodiment of the invention is shown, which is described below, showing:
Fig. 1 a gas bag module in a diagrammatic side view,
Fig. 2 a perspective view of a part of the gas bag module with the openings serving to secure the protective covering.
The gas bag module which can be seen from Figure 1 has a housing 10 with a housing base 11 and lateral housing walls 12. The side 13 of the housing 10 lying opposite the housing base 11 is constructed so as to be open. The upper edge of each housing wall 12 is bent around into an outwardly protruding flange 14 laterally from the housing wall 12.
An inflatable gas bag 16 is folded into the interior of the housing 10, which bag is connected in the deepest part of the housing in the region of its housing base 11 to a gas generator 15, which projects with a partial region through the housing base 11 into the interior of the housing 10. It can be seen that the folded gas bag 16 projects at the top over the open side 13 of the housing 10. A protective covering 17 is secured by its one end 18 through the gas generator 15 in the interior of the housing 10 and is guided up along a lateral housing wall 12, encompassing the gas bag 16 externally, in the direction of the open side 13 of the housing and then, overlapping the open side 13 of the housing 10, is flapped over the upper region of the folded-in gas bag 16. Openings 20 are let in the opposite flange 14, which immediately adjoin the transition between the housing wall 11 and the flange 14, so that a tongue 22, constructed on the turned over free end 19 of the protective covering 17, is able to be inserted through the respective opening 20. A holding nose 21 is formed, projecting from the housing wall 11 into the interior of the opening 20, which is able to be inserted through the opening 20 in the flange 14 to secure the free end 19 of the protective covering 17 on the housing 10, and is to be secured by means of a holding recess 23, formed in the tongue 22, on the holding nose 21. As the gas bag 16, folded in the housing 10, protrudes slightly over the open side 13 of the housing 10 and exerts a certain packing pressure against the protective covering 17 which is spanned over it, the tongue 22 of the protective covering 17, which is mounted with its holding recess 23 into the holding nose 21, is held under tension, so that the protective covering 17 is secured sufficiently on the housing 10.
On the side of the housing lying opposite the fastening of the protective covering 17 on the flange 14, the flange 14, running there, is provided with fastening openings 24 for the screwing on of the housing 10 on a part which is fixed to the vehicle.
It can be seen from Figure 2 that in . the respective flange region of the housing 10, two openings 20 are provided with holding noses 21, which are arranged alternating with three fastening openings 24, for fastening the housing 10, formed in this region of the flange 14. It can be seen that the openings 20 directly adjoin the transition between housing wall 11 and flange 14, so that the tongue 22, which is able to be guided through the corresponding opening 20, can be secured lying closely against the upper edge of the housing 10. In this way, the occurrence of gores is prevented, which would occur for example if the free end 19 of the protective covering 17 were drawn over the outer edge of the flange 14 and were secured here. In such a case, in fact on mounting of the gas bag module, parts of the gas bag 16, which is folded into the housing 10, could be placed over the upper edge of the housing wall 12 or between flange 14 and protective covering 17 drawn over it, and through the occurrence of kinks caused thereby, damage could occur to the gas bag 16. Also, it would not be ruled out that on unfolding, the gas bag 16 moves into such a gore and therefore an unsymmetrical stressing of the protective covering 17 is brought about with an unintentional tearing. It can be seen that the holding nose 21, projecting into the opening 20, is arranged so as to be sunken with respect to the surface of the flange 14, which lies on the side of the housing facing away from the gas generator 15. Hereby, a jamming is prevented of the protective covering 17 or of its tongue 22 between the transition of the housing wall 12 to the flange 14 by a vehicle part, such as instrument panel or steering wheel cover, placed onto the upper side of the gas bag module. Furthermore, the transition between housing wail 12 and the flange 14, protruding therefrom, is constructed with a rounding 25 in the region of the opening 20, so that also hereby damage to the tongue 22 of the protective casing 17 is avoided.
The features of the subject of these documents, disclosed in the above description, the claims, the abstract and the drawings, can be essential for the realization of the invention in its various embodiments both individually and also in any desired combinations with each other.
